"The New York Department of Transportation has pointed to research that shows that most bridge strikes occur because of incorrect GPS information, commonly caused by drivers using consumer-targeted software instead of GPS software designed for commercial use. Programs like Google Maps dont know the difference between a driver driving a semi and a driver behind the wheel of a car, so while it can get you from point A to point B, you always need to be sure youre keeping an eye out for warning signs. Be especially careful if youre one of the over 5 million Americans who bought an iPhone 5. The new Apple Maps app is widely reported to take round-about routes or not even get you to your destination at all! With no way to regulate consumer software, the NYDOT is recommending that commercial drivers be prohibited from using them."
